To all whom 'it muy concern.' 1

Be it kno-wn that i, 'Wimmer C. HART- MANN, a citizen of the United States, residing,` at Milwaukee, county of Milwaukee, and State oi Wisconsin, have invented new and useful lmproveniente in Cream-Separatore, of which the following is a specification.

My invention relates to improvements in that class ot cream separators in which the separating cones are supported. from and around the lower end of a revoluble central member, a milk receiving' chamber is centrally located in the upper end of said central member, a plu ality of vert-ical channels are supported from thev periphery of and at the lower end of said central meinber, and radial ducts extend outwardly from the lower end of said milk receiving` chamber to each of said vertical channels, whereby the unseparated milk is caused to flow outwardly of its own gravity from said central milk. chamber into said channels before passing out through the radial apertures into the space between the separatin,r cones and whereby, owingl to the greater distance oil said channels from the center ot saidmilk chamber, the centrifugal action at such point is greatly increased, and the mill( is caused to move with much greater velocity, My present improvement, however, pertains more especially among other things, to the peculiar construction of said vertical channels.

My invention is further explained by ref erence to the accompanylug` drawings, in Which- Figure l. represents a vertical section, drawn on line aff-m of Fir: 3, the right onehalt of the central member being shown in full. Fig. 2 is a top view of the central member, part broken away. 3 is a trans Verse section ot the central member, drawn on line .i/jz/ of l, and Fig. el is a vertical section tlirougli one of the milk chan-- nels, drawn on line me of Fig. 3.

Like parte are ident-ined by the same reference numerals throughout the several views.

The central member comprises the milk receiving chamber l, the three vertical chan` nels 2 and the conical base member 3, provided with the annular channel l for the re ception of the lower end of the inclcsing case l l l l l 1 l l i l I I i r 5, and the radial ducts 5 which communicate from the lovver end ot' the milk chamber With the upper end of said vertical channels. 6, 6, represent a series oit milk separat-ing cones, Which are supported, one above an other, from and around the base member 3 in the ordinary manner. The central member, together with the inclosing case 5 are sugo ported from the revoluble shaft 'l' through and by which motion is communicated to said parts trom the driving mechanism of the separator. Novelty of invention is predicated more especially, as stated, upon the peculiar construction oit the vertical channels 2, Which channels are cast or otherwise formed `integral with the central member and ,are each provided at one ont their outer corners with a vertical. series or outlet apertures 8, 8, through which as the same is volved, the milk is discharged by the centrifulgal action ot the machine. The vertical channels 2 are also provided at their inner corners upon the side opposite from said vertical series ot' apertures with a ver ical slot 9.

lt will be understood that the central member and the several cooperating` parts are adapted to be'rapidly revolved in the direction indicated by the arrows l0, shown in Figs. 2 and 3, whereby the heavier prod-I ucts of the milk are caused. by its centrifugal action to be discharged with greatvelocity out through said apertures 8 in the opposite direction trom that of rotation, -While an ad` ditional impulse Vis communicated to i milk by contact of the air which is caused by such rotation to enter said vertical chan nels through the vertical slot 9'. t-Will be obvious that by the cooperation the air thus admitted, and the centrifugal action of the milk produced by the rapid rotation ot said channels, the discharge of the milk 'trom such channels is greatly accelerated. A further object attained by the vertical slots is found in the that they provide access to said channels the purpose. of cleansing the same for removing such foreign substance as might otherwise accumulate therein. lt will also be understood that the milk which through the series of apertures 8 enters the spaces betvveen the respective cones, Y,vh by ,the centrifugal action, to pz flo'vvnH W'ardly and outwardly 'through it is caused /verticul Sides Wi :and from thence upwardly through the :space 1.3 between the periphery of said conce` and the inclosing case 5 and from thence out through the duct lll to the place oit die charge, while the cre-nin end other products or the millt o" less epecitic gravity pass up 'through the spaces l5 between Suid vertical ci ennelea 'thence through the channel 'r6 und from thence out through the ducts 17 to the place oit disch-erge.

Having thus described iny'invention, what l claim es new, and desire to secure by Lettif lletent, is-

ln cream separater oit the described ch e, the combination of :ir revoluble central member provided et it-s upper end with e, r ilk receiving chamber, a plurality of Sepe ng cones su ported from and around @eid member :15p urelity of vertical channels i haring open'coinrnunication with Suid'v milk receiving chamber projecting radially beyond 'the peri hery of seid central member and reepective y provided upon one of their t a vertical slot and upon the opposite side with e plurality of outlet apertures respectively registering' with theA spaces between said separating cones.

2. lin a cream separetor of the described clues, the combination of a revoluble central member provided at its upper end with a milk receiving chamber und :it its lower end With a, plurality ot' vertical channels, radial.

being respectively provided upon one side t with aplurality of outlet apertures respectively registering with the spaces between said sepnratin cones and upon their op.- posite sides with a. vertical slot, all substantially as and for the purpose specified. ln testimony whereof l atlix my signature in the presence of two Witnesses.
